This seems like overkill as well.  why don't we just pass the frequence as a
double?

Removed, will consider adding it back once we have more data to be passed in
configuration.

+    private final double mFrequency;
+
+    PlatformSensorConfiguration(double frequency) {
+        mFrequency = frequency;
+    }
+
+    @CalledByNative
+    private static PlatformSensorConfiguration create(double frequency) {
+        return new PlatformSensorConfiguration(frequency);
+    }
+
+    @CalledByNative
+    public double getFrequency() {
+        return mFrequency;
+    }
+}
